Dyson Fans - wow!!!


YouTube description: “Air is accelerated through an annular aperture and over a 16° airfoil-shaped ramp, generating an uninterrupted stream of smooth air.”

Testing the Dyson Air Multiplier™ fan
YouTube description: “Hundreds of tests were carried out to reveal the ideal ramp angle, aperture width and loop amplifier dimensions of the Dyson Air Multiplier™ fan.”

Balloons and Dyson Air Multiplier™ fans
YouTube description: “One balloon and a couple of evenings after work -- Dyson engineers show how inducement and entrainment works on the Air Multiplier™ fan. If you watch closely, the balloon is sucked into the airflow from behind and to the side of the fan; this is inducement and entrainment of the air. Lots of experimentation with different sized balloons and other objects produced this video. And although edited to include our successful attempts, the video is made from completely genuine footage (and no, the balloon isn’t attached to anything). Find out more at: Disclaimer: This was created and executed by trained Dyson engineers under a controlled environment. Do not attempt to duplicate.”
